Subject: [PATCH 0/2] mm: Fix N_CPU handlings of node_states

node_stats[N_CPU] tracks which nodes have CPUs on the system.
vmstat.c updates this N_CPU information, but it has multiple
issues. 

Patch 1/2 changes setup_vmstat() to set up the N_CPU info at
boot.  Patch 2/2 changes vmstat_cpuup_callback() to udpate
the N_CPU info at CPU offline.
